Actress Sonali Kulkarni, who was paired opposite Saif Ali Khan in 'Dil Chahta Hai', said they never thought the song 'Woh Ladki Hai Kahan' would become a classic. "The atmosphere in that unit was fun-filled. The rehearsals for that song happened with...laughter in just 15-20 minutes," she said. Sonali added even today she gets welcomed with the song.
